A* 是一种最佳优先搜索算法,用于在图中找到最优成本路径。A* 从并行性中受益匪浅,因为在许多应用程序中,A* 受到内存使用的限制,因此使用集群上所有聚合内存的A* 的分布式内存实现可以解决串行单机实现无法解决的问题。我们调查的方法,并行A*,集中在分散的方法,A* 处理器之间的状态空间分区。我们还调查的方法,如并行IDA* 的并行,内存有限的变种。
A* is a best-first search algorithm for finding optimal-cost paths in graphs. A* benefits significantly from parallelism because in many applications, A* is limited by memory usage, so distributed memory implementations of A* that use all of the aggregate memory on the cluster enable problems that can not be solved by serial, single-machine implementations to be solved. We survey approaches to parallel A*, focusing on decentralized approaches to A* which partition the state space among processors. We also survey approaches to parallel, limited-memory variants of A* such as parallel IDA*.
